HORATIO BATEMAN, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO XVM. F. BATEMAN, OF HARVARD, MASSACHUSETTS.

VAPOR-LAMP.

Specification of Letters Patent No. 20,886, dated May 25, 1858.

T o (LIZ whom it may concern:

Be it known that I7 Hona'rro BATEMAN, of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Fluid-Lamps; and I do hereby declare that the following is a full and exact description of the same7 reference being had to the accompanying drawings and to the letters of reference marked thereon.

My invention relates to an improvement in that class of fluid lamps in which gas is generated by heat imparted to a Wick Which does not come in contact With the flame, the Wick being heated for the purpose of generating the gas by means of a spur or tongue extending' into the Wick. My improvei'nent consists in the peculiar construction of the said tongue or spur.

In order to enable others skilled in the art to make and use my invention, I Will now proceed to describe its construction and operation, reference being had to the drawings which form a part of this specification.

Figure l is a central vertical section ol" a liuid lamp with my improvements applied thereto. Fig. 2 is a view of the tongue or spur.

In my improved lamp a represents the reservoir or receptacle for the fluid.

Z) is the Wick7 o the Wick tube and d the cap arranged as shown in F 1g. 1. The spur or tongue e is screwed into the hollow stem of the cap cl and has a hole or eye f formed near its bottom. Through this eye f the Wick b is drawn and held in place. The gas generated issues through the small holes g g.

In these kind of fluid lamps, the insertion of the spur or tongue, which is to heat the Wick. as ordinarily constructed crowds down and displaces the Wick sometimes amming the wick so tightly against its tube as to cause it to gum up and thereby prevent the light from burning freely. By constructing the tongue with the eye f it Will be seen that this ditliculty is obviated, as the Wick is held in the spur or tongue and moves with it, and can not possibly be displaced or jammed in the Wick tube o.

Having thus described my improvements I shall state my claim as follows:

That I claim as my invention and desire to have secured to me by Let-ters Patent is- Constructing the spur or tongue e With a suitable eye for the insert-ion and retention ot' the Wick, as set forth.
